VII. — Report on the Experiments ivifh Clovers at Woburn. By 
Wm. Carkuthees, F.R.S., Consulting Botanist to the 
Society. 
These experiments were instituted with the view of observing 
the duration of the life of the different species of clover in 
ordinary cultivation. While this was being tested, it was 
resolved, on the recommendation of the late Dr. Voelcker, to 
try the value of different manures, and see if the action of these 
manures on the clovers would throw any light on clover sickness. 
Plots were set apart for the experiments, both in the Stackyard- 
field, with its light sandy soil, and in the Warren-field, with its 
heavy loam. Each plot was twelve feet square. Six different 
samples of clover were sown under seven different kinds of 
treatment ; there were consequently in each field forty-two plots. 
The clovers sown were two samples (A. and B.) of perennial 
red clover, one each of cowgrass and alsike, and two of 
white clover, one of them purporting to be English grown, the 
other Dutch. One of the plots had no manure. The second 
plot had at the rate of 4 cwt. of bone-dust and 4 cwt. of super- 
phosphate to the acre. The third plot had at the rate of 4 cwt. 
of sulphate of potash to the acre. The fourth plot at the rate 
of 2 cwt. of sulphate of ammonia. The fifth plot at the rate of 
2 cwt. of nitrate of soda. The sixth plot at the rate of 4 cwt. 
of bone-dust, 4 cwt. of superphosphate, 4 cwt. of sulphate of 
potash, and 2 cwt. of sulphate of ammonia. And the seventh 
plot had at the rate of 4 cwt. of bone-dust, 4 cwt. of superphos-
